ABSTRACT CLASS (SOYUT SINIF)<\/strong><\/p>\n

    \n
  1. Tasar\u0131m\u0131 zarif hale getiriyor.<\/li>\n
  2. Teknik tan\u0131m\u0131 en az bir tane soyut y\u00f6ntem i\u00e7eren s\u0131n\u0131ft\u0131r.<\/li>\n
  3. Soyut y\u00f6ntem demek alt s\u0131n\u0131fta tekrar tan\u0131mlanmas\u0131 zorunlu y\u00f6ntem demektir.<\/li>\n
  4. E\u011fer bir s\u0131n\u0131f \u00fcst s\u0131n\u0131f\u0131n y\u00f6ntemlerinden birini bile i\u00e7ermiyorsa o s\u0131n\u0131fta soyut olur.<\/li>\n
  5. De\u011fi\u015fkenler soyut olamaz ancak y\u00f6ntemler soyut olur.<\/li>\n
  6. Soyut s\u0131n\u0131flarda asla kod yaz\u0131lmaz. Sadece y\u00f6ntemin imzas\u0131 kullan\u0131l\u0131r.<\/li>\n
  7. Soyut bir s\u0131n\u0131f\u0131n yap\u0131c\u0131 tan\u0131ml\u0131 olsa bile asla nesnesini yaratamay\u0131z. Di\u011fer bir deyi\u015fle soyut bir s\u0131n\u0131f asla bir nesnenin ger\u00e7ek tipi de\u011fildir.<\/li>\n<\/ol>\n

    Soyut bir s\u0131n\u0131f\u0131n alt s\u0131n\u0131f\u0131;<\/p>\n

    • Ona miras kalan abstract y\u00f6ntemlerinin en az birini bile tan\u0131mlamazsa oda soyuttur.<\/li>\n<\/ul>\n

      INTERFACE (ARAY\u00dcZ)<\/strong><\/p>\n

        \n
      1. Bir aray\u00fcz i\u00e7inde hi\u00e7bir \u00f6zellik bulundurmaz. \u0130\u00e7erisinde de\u011fi\u015fken olmaz.<\/li>\n
      2. Bir aray\u00fcz sadece soyut y\u00f6ntemler bulundurur. Soyut s\u0131n\u0131flar gibidir. Ama s\u0131n\u0131f de\u011fildir.<\/li>\n
      3. Java da bir alt s\u0131n\u0131f\u0131n birden fazla \u00fcst s\u0131n\u0131f\u0131 olam\u0131yor ancak bir s\u0131n\u0131f\u0131n birden fazla uygulad\u0131\u011f\u0131 aray\u00fcz\u00fc olabilir.<\/li>\n
      4. Aray\u00fczler de\u011fi\u015fken tan\u0131m\u0131nda kullan\u0131labilen bildirim tipleridir.<\/li>\n
      5. \u00c7oklu aray\u00fcz uygulama \u00e7oklu kal\u0131t\u0131mdan (multiple inheritance) farkl\u0131, \u00e7\u00fcnk\u00fc kod miras\u0131 kalm\u0131yor. Ancak bir aray\u00fcz kal\u0131t\u0131m ile (extends) ba\u015fka aray\u00fczlerden t\u00fcretilebilir.<\/li>\n
      6. Bir aray\u00fcz\u00fcn alt aray\u00fcz\u00fc olabilir. \u00dcst aray\u00fczden, alt aray\u00fcze t\u00fcm y\u00f6ntem bildirimleri miras kal\u0131r.<\/li>\n<\/ol>\n
